FPSO Sangomar External Turret
Scope of Work
SOFEC will design, construct, and fabricate an external turret for the Sangomar (formerly SNE) Field Development Phase 1 project located in the Sangomar Offshore and Sangomar Offshore Deep oil blocks, located offshore Senegal.
The FPSO will be deployed at the Sangomar field located approximately 100 kilometers south of Dakar, Senegal. The Sangomar Field Development is expected to be Senegal’s first offshore oil development. Scheduled for delivery in early 2023, the FPSO vessel will be permanently moored at a water depth of approximately 780 meters.
The FPSO will be capable of processing 100,000 barrels of crude oil per day, 130 million standard cubic feet of gas per day, 145,000 barrels of water injection per day and will have minimum storage capacity of 1,300,000 barrels of crude oil.
The SOFEC external turret mooring system will be ABS classed.
